frac = 0.001 ‰

‰ = ppk = ppt

wt% = 10 ‰ =0.01 frac

mg/L = 1 wt% = 10 ‰ ^*

^* In engineering practice Salinity is often measured in [ mg/L ] = 0.01 wt% but this is misnomer as the right-hand side is dimensionless quantity whereas the left-hand expression has a physical meaning of the density.

The relation between the two has only sense for water at melting point which has a unit density.
